The 8(a) Business Development Program is one of the most powerful tools available to a socially and economically disadvantaged small business owner. For construction firms specifically, it opens the door to sole-source awards and competitive set-asides with federal agencies that spend billions on construction every year. The U.S. Army Corps of Engineers, Department of Veterans Affairs, and General Services Administration together obligated over $20 billion in construction contracts in FY2023, according to USASpending.gov. A significant share of that flows through 8(a) and other small business set-aside vehicles.
This guide is for the owner of a construction company who already knows what 8(a) is and wants to understand the specific eligibility requirements and nuances that apply to their industry.
Who qualifies for 8(a)
The SBA runs the 8(a) program under 13 CFR Part 124. The core eligibility criteria apply regardless of industry:
- The firm must be at least 51% owned and controlled by one or more socially and economically disadvantaged U.S. citizens
- The disadvantaged owner(s) must manage day-to-day operations and make long-term decisions
- The firm must qualify as a small business under its primary NAICS code
- The owner's adjusted gross income for the three-year period prior to application must average $400,000 or less (with some exceptions), and their personal net worth must not exceed $850,000 excluding equity in the primary residence and ownership interest in the applicant firm
- The firm must be in business for at least two years (the SBA may waive this under limited circumstances)
For construction companies, the primary NAICS codes are typically 236220 (Commercial and Institutional Building Construction) and 237310 (Highway, Street, and Bridge Construction), though your firm may operate under others in Division C of NAICS. Each code has its own SBA size standard.
Size standards for construction NAICS codes
This is where construction companies often trip up. The SBA does not use a single size standard for construction. It depends on your primary NAICS code.
- NAICS 236220 (Commercial and Institutional Building Construction): $45 million average annual receipts
- NAICS 237310 (Highway, Street, and Bridge Construction): $45 million average annual receipts
- NAICS 236115 (New Single-Family Housing Construction): $45 million average annual receipts
- NAICS 238110 (Poured Concrete Foundation and Structure Contractors): $22.5 million average annual receipts
The SBA uses a three-year average of annual receipts to determine size. If you are approaching those thresholds, apply soon. Firms that graduate out of size standards lose eligibility even before their nine-year 8(a) term ends if they exceed the limit.
You can verify the current size standard for any NAICS code at the SBA's size standards tool at sba.gov/size-standards.
Licensing and bonding requirements specific to construction
Federal construction contracts come with requirements that most private projects do not. The Miller Act (40 U.S.C. §§ 3131–3134) requires performance and payment bonds on federal construction contracts exceeding $150,000. This is not an 8(a) requirement. It is federal law. Your bonding capacity directly limits the size of contracts you can pursue.
Before you apply for 8(a), get your bonding house in order:
- Work with a surety agent to establish or increase your bonding limit
- Document your backlog, equipment, and financial statements properly because sureties underwrite your balance sheet
- Smaller firms often start at $500K–$1M bonding capacity; scaling to $5M or more opens the mid-tier federal construction market
State contractor licensing is a separate layer. Federal agencies do not issue licenses, but they require compliance with state and local licensing laws in the jurisdiction where the work is performed. The SBA will not block your application over licensing, but an agency's contracting officer can and will require proof of proper licensing before awarding a contract.
The ownership and control requirement in construction
Construction businesses often have partners who contribute labor, equipment, or bonding relationships. The SBA's ownership and control requirements are strict. The disadvantaged owner must:
- Hold at least 51% of voting stock or membership interest
- Receive compensation commensurate with their ownership stake (you cannot have a disadvantaged owner on paper while a non-disadvantaged partner takes 80% of the profit)
- Actually run the company day-to-day, meaning they set bid strategy, manage project managers, sign contracts, and make hiring decisions
If a non-disadvantaged spouse, business partner, or equipment lender has unusual control or influence over the firm, the SBA will flag it. Bonding relationships are a common issue. If a surety requires a non-disadvantaged co-signer on the bond as a condition of coverage, document why this does not give that person control over the business.
What federal construction contracts look like under 8(a)
The federal government awards 8(a) construction contracts through two mechanisms:
Sole-source awards are available for contracts valued under $4.5 million (or $7 million for construction work meeting the DoD threshold). The contracting officer can direct the contract to your firm without competition. This is the fastest path to your first federal contract. Agency small business offices often maintain lists of 8(a) firms they have worked with or want to work with.
Competitive 8(a) set-asides require multiple 8(a) firms to compete, but the pool is limited to 8(a) participants. This is standard for contracts above the sole-source threshold.
A concrete example: the VA regularly awards 8(a) set-aside contracts for minor construction and renovation at VA medical centers under NAICS 236220. Contract values typically range from $500,000 to $4.5 million per award. A VA regional office may issue 10–30 such awards per year in a given region. The VA's Office of Small and Disadvantaged Business Utilization publishes forecasts at va.gov/osdbu.
The application itself
The 8(a) application is submitted through the SBA's Certify.SBA.gov portal. For a construction firm, expect to provide:
- Three years of tax returns (personal and business)
- Three years of financial statements
- Articles of organization or incorporation, operating agreement or bylaws
- Proof of ownership (stock certificates, membership certificates)
- Résumé or narrative demonstrating the disadvantaged owner's experience managing the business
- Narrative explaining how the owner is socially disadvantaged (required unless the owner belongs to a presumptively disadvantaged group under 13 CFR 124.103)
The SBA reviews applications in roughly 90 days, though complex cases take longer. Common rejection reasons for construction firms include insufficient documentation of owner control, missing financial statements, and failure to meet the personal net worth threshold.
Joint ventures and mentor-protégé
Once certified, you can pursue work that exceeds your current capacity through joint ventures. The SBA's mentor-protégé program lets an 8(a) firm team with a larger company and bid as a joint venture on contracts of any size, as long as the 8(a) firm performs at least 40% of the work (for construction, this is set out in 13 CFR 125.6).
This is a significant lever for construction firms. A joint venture with an established prime contractor gives you access to their bonding capacity, equipment, and past performance record while you build your own. The joint venture agreement must be pre-approved by the SBA's district office.
How NAICS codes affect your set-aside opportunities
When a contracting officer lists an 8(a) set-aside opportunity, they assign a primary NAICS code to it. Your firm must have that NAICS code listed in SAM.gov to be eligible to bid. Most construction firms should register multiple NAICS codes in SAM.gov to maximize the opportunities they appear eligible for.
For example, a firm primarily doing commercial construction (236220) should also register for applicable specialty trade codes such as 238910 (Site Preparation Contractors) or 238990 (All Other Specialty Trade Contractors) if they self-perform any of that work. Each code must accurately describe work your firm actually performs.
Staying compliant during your nine-year term
The 8(a) program runs nine years, split into a four-year developmental stage and a five-year transition stage. During this period:
- You must submit annual reviews to the SBA including updated financials
- You must report contracts awarded, modifications, and terminations
- Your annual revenues and personal net worth are reviewed; graduating out of size standards or exceeding net worth limits can trigger early termination
- You must continue to meet the "unconditional ownership" standard; any transfers of ownership require SBA approval
Construction firms that win large multi-year contracts should project their revenue trajectory. Winning a $20M construction contract in year three of your 8(a) term may push your three-year revenue average above the size standard by year five.
How to apply
- Register your firm in SAM.gov if you have not already. You need an active SAM.gov registration to apply for 8(a) and to receive any federal contract.
- Verify your firm's size under your primary NAICS code using the SBA size standards tool.
- Gather three years of personal and business tax returns and financial statements.
- Document your ownership and control clearly, including operating agreements, corporate bylaws, and any partnership or shareholder agreements.
- Apply at certify.sba.gov.
- Contact your local SBA District Office after submitting. Analysts can flag issues before a formal denial, and many offices hold informational sessions for construction firms.
The SBA also maintains a list of Procurement Technical Assistance Centers (PTACs) — now called Procurement Technical Assistance Program (PTAP) offices — that provide free counseling on 8(a) applications and federal contracting. Find your nearest office at aptac.org.
